Transmission Media Question & Answers

November 3, 2022 By WatElectronics

This article lists 100 Transmission Media MCQs for engineering students. All the Transmission Media Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Transmission Media. 

In data communications, physical paths are established between the receiver and a transmitter that allows sending data referred to as the Transmission medium. It is a type of channel that establishes communication between the receiver and the sender. Data is transmitted in the form of Electromagnetic signals.

Through transmission, medium information is carried through a Local Area Network (LAN) in bits format. If the network is based on copper, bits are transferred as Electrical signals. For a network based on optical-fiber bits are transferred as Light pulses.

For an Open System Interconnection transmission medium present in the first layer i.e., referred to as Physical Layer. Medium and signal characteristics determine the transmitted data's quality. Each transmission medium has distinct properties.

Transmission Media is categorized into two types. They are Guided and Unguided media. Guided media is referred to as the Bounded or wired media of transmission. These are preferred to transmit data for shorter ranges. Unguided Media is a wireless media of transmission that is unbounded. Signals in such media are broadcasted via air and are preferred for a larger range of distances. Satellite communication is a part of unguided transmission.
